Phylogenetic data for: High diversity of new and known Phytophthora species from phylogenetic Clade 10 in natural ecosystems of Asia, Europe and the Americas

During extensive surveys of Phytophthora diversity, 14 new species were
detected in natural ecosystems in Chile, Louisiana, Sweden, Ukraine,
Vietnam and Indonesia. Multigene phylogeny based on the nuclear LSU,
rpl10, ITS, ßtub, enl, hsp90, tef-1α, ras-ypt1 and tigA and the
mitochondrial cox1, nadh1 and rps10 gene sequences demonstrated that they
belong to phylogenetic Clade 10 which is structured into three subclades.
Subclades 10a and 10b comprise soil- and waterborne species with
nonpapillate sporangia and variable breeding systems, including the known
P. afrocarpa, P. gallica and P. intercalaris and the new P. ludoviciana,
P. procera, P. pseudogallica, P. scandinavica, P. subarctica, P.
tenuimura, P. tonkinensis and P. ukrainensis. In contrast, all species in
Subclade 10c are airborne with papillate sporangia and homothallic
breeding system, including the known P. boehmeriae, P. kernoviae and P.
morindae and the new P. celebensis, P. chilensis, P. javanensis, P.
multiglobulosa, P. pseudochilensis and P. pseudokernoviae. All new species
differed from each other and from related species by a unique combination
of morphological characters, the breeding system, cardinal temperatures
and growth rates. The biogeography and evolutionary history of Clade 10
are discussed and the hypothesis put forward that the extant subclades
originate from early divergences of pre-Gondwanan ancestors (>175
Mya) into water-/soilborne and airborne lineages which during their global
spread experienced multiple allopatric and sympatric radiations.
